To all whom it may concern:

Be it known that I, HANS MIKOREY, a civil engineer and a subject of the German Emperor, and a resident of 13 Wartburgstrasse, in the city of Schbneberg, near Berlin, Kingdom of Prussia and German Empire, have invented a certain new and useful Color-Spraying Apparatus, of which the following is a specification.

This invention has reference to a spraying apparatus, which is particularly intended for the spraying or disintegrating of colors or dye studs and which is distin uished b a pecul-- iarly shaped dashing or abutting p ate.

Atomizers or sprayers in combination with abutting surfaces have already been variously suggested; these abutting or dashing surfaces however did not serve the purpose of disintegrating or spraying, but they merely served for the deflection of an already atoniized jet from its original direction or for the regulation of the e'lllcient coloring substance. Thus for instance, one of the sprayers or disintegrators or atomizers now in use, possesses a gutter shaped abuttingsurface, which however does not participate in the distribution of the color or dye-stuff, but which serves exclusively for the purpose of deviating the current of air which isalready charged with the disintegrated color, in any desired direction. In another atomizer or spra er, which is arranged, so as to form part 0 a machine, and.v which serves for the automatic roduction of different shades of colors blen ed into each other, dashing or abuttin surfaces are provided at an an le to the-direction of the current of air. T liese abutting or dashing s'urfaces are so near to the surface to be covered with color and they are arranged at such a distance from the air delivering nozzle, that the color is merely reflected in a certain direction, the current of air;havin no further influence uon the movement of t e deflected particles 0 color or dye stuff. The particles of color on the contrary continue their way in the direction, imparted to them by the inclination of the abutting or dashing surface and are thrown upon the surface to be covered with color, in regulated proportion. According to the inclination o the dashing or abutting plate and the thereby resulting an le of deflection, which is different for the different parts of the cone of jets striking against the abutting body, the same amount of color will be distributed upon a larger or smaller number of surface units of the surfaceto be colored, and the blending of shades of color is thereby accomplished. Furthernozzle. This cone is likewise merely a d1- recting surface for the purpose, to expand a cylindrical jet of water into a hollow cone of water, closed all around. As compared with these well known constructions, the herein described sprayer or atomizer, which is intended for manual 0 eration is distin uished by the fact, that t e abutting or ashing p ate is arranged substantially vertically in relation to the direction of the air current, in order to contribute to the increase of the .spraying'action and with a view of producing as fine a mist of color as possible.

The abutting or dashing plate is very narrow in one of its two dimensions and at right angle to the direction of the impinging air current and itis also arranged near to the air and color delivering nozzle; hence the mist of color, originated from the abuttingior dashing surface is still struck by the air current issuing from the air pressure nozzle, so that a certain definite direction, which is approximately that of the air current can be imparted to the entire mass of the mist. On the surface on which the mist of color impinges and which is to be coated, the color is put on everywhere at a uniform thickness. The graduation of shades of color for obtaining artistic effects is done 1) tistic individuality can e imparted to the work.

On the drawing an embodiment of the subject matter of the invention is shown'by way of example, a being the color delivering. nozzle, which is arranged above the pressure air nozzle 6 ingthe well known manner. In front of the nozzle b the abutting or dashing plated of little height and of suitable breadth 1s arranged which might be exchangeably secured in such a manner, that the jet of air and of color of dye stuff will strike against it in a vertical or approximately vertical direction.

In order to be able to change the efficiency of' the spraying or disintegrating action by inclining the abutting or dashing plate or by moving it up and down, the dashing plate is preferably connected to a s ring acting plate 0 or made in one piece witih the same. By means of a set screw 8 connected in a suitable hand, sothat 81'? manner to the nozzle pipe I), the plate a and consequently the abutting or dashing plate 41 also may be differently inclined or a justed in a vertical direction.

The arrangement of the abutting or dashin plate (1 is also applicable in the case of 00 or or dye-stuff isintegrators, in which the color delivering nozzle is arranged below the air pressure nozzle.

What I claim and desire to secure by Let-- ters Patent of the United States is Sprayer for liquid colors comprising a color tube a and an air tube b arranged at an angle to each other, a resilient dash plate 0 secured to the nozzle 1) near the opening ofthe nozzle a, with a deflector d in 11118 with the nozzle b, a set screw e in a bar rigidly connected to the nozzle 1) and adapted toact on the dash plate 0 substantially as described and for the purpose set forth.

In witness whereof I have hereunto signed my name this eighth day of May 1907, in the presence of two subscribing witnesses.

HANS MIKOREY.
